Foundation piles are structural elements that allow reaching the most resistant soil layers located at depth. Discover how to design them<\/p>\n

<\/p>\n

There are situations where it is not possible to find sufficiently resistant soil on the surface to safely and stably support a structure. However, thanks to deep foundations and in particular to foundation piles, it is possible to effectively solve this problem.<\/p>\n

In the following article, we will explore the different types of foundation piles, each with specific characteristics. We will see how these elements can be used according to the project’s needs and the soil characteristics. We will also provide some useful tips for their design.<\/p>\n

Structural engineering professionals can rely on advanced systems to improve accuracy in designing pile foundations and other structural elements. Experience for yourself the potential of a structural calculation software<\/a> to optimize your work.<\/p>\n

Thanks to the synergistic integration between BIM technology<\/strong> and FEM analysis<\/strong>, you can combine the three-dimensional representation of models with powerful structural analyses. You will save valuable time and eliminate the risk of human errors through automated calculations and advanced simulations that take into account multiple variables.

What are foundation piles?<\/h2>\n

Foundation piles are structural elements that fall into the category of \u201cdeep or indirect foundations\u201d<\/strong>, as they have the ability to transfer the vertical load of the structure to more resistant and stable soil layers<\/strong> located at greater depths.<\/p>\n

Unlike shallow foundations, which transfer the load to the ground only through the bearing plane, pile foundations transmit the load both by friction<\/strong> along the lateral surface of the foundation and by point load<\/strong>, depending on the ratio between the pile diameter and its height.<\/p>\n

They can be made of different materials<\/strong>, such as reinforced concrete, steel, or wood. They are cast in place or driven into the ground to reach the bearing layers and provide the necessary resistance against external forces that would not be manageable by a shallow foundation.<\/p>\n

The main objective of foundation piles is to reduce long-term settlements, exploiting the mechanical characteristics of deep substrates and avoiding issues related to the presence, in the superficial layers, of soft soils, water tables, or voids.<\/p>\n

When to use foundation piles?<\/h2>\n

Among the different types of foundations that can be used to ensure the safety and stability of a structure, it is generally advisable to rely on foundation piles when:<\/p>\n
